The reality star and her famous sisters recently launched a fashion collection at Dorothy Perkins, and reportedly send the Duchess a load of free clothing, only to get them send straight back.
According to The Examiner, Kate politely declined to accept any of the free clothing received from the famous reality star.
The Kardashian Kollection features a lot of figure-hugging silhouettes, with leopard print and studs - not exactly appropriate for a member of the Royal family.
A palace insider told the magazine: 'Kate is hardly going to turn up for an event with the queen in a cheap leopard-print miniskirt or gold sequined jacket.'
The Examiner source also claims Kim invited Kate over for tea, in an attempt to get a new royal best friend out of her recent trip to London. But once again, the Duchess politely declined the offer.
A friend close to Miss Kardashian rubbished the claims and said: 'Kim never asked Kate to lunch. She was there (in England) working for a few days.'
